The 2.5 Liter Mercury Champ race outboard is the premier power for the Champ Boat Series outboard tunnel boat racing circuit. The compact engine spins 8600 rpm to power Champ class tunnel boats to speeds in excess of 130 mph!
 

The OptiMax 200XS SST race outboard is poised to revolutionize SST 120 racing in North America! The engine made history in 1999 when it was the first low-emissions outboard to win the grueling 24 Hours of Rouen endurance powerboat race in Rouen, France. The engine placed first in Class 2 competition at the 2004 Rouen event and finished fourth, sixth and ninth overall. The direct fuel injected 2.5 Liter V-6 powerhead is mounted on a 12-inch race center section mounted on a VI SSM gearcase.
